SPECIFICATION forming part of Letters 'Patent No. 580,988, dated April 20, 1897.

Application tiled December 3, 1895. Serial No. 570,874. (No model.)

To all whom t may concern,.-

Be it known that I, DANIEL MCFARLAN MOORE, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Interruptor, et which the following is a specification.

My invention relates to circuit-interrupters which are operated in a closed receptacle herio inetically sealed for the purpose of preserving the vacuum in which the interrupter works, and is designed more particularly as an improvement upon such interrupters when operating in a circuit of induction wherein the interruptions set up electric pulsations or disturbances that may be employed for producing light, as described in my Iatent No. 548,127, or may be used for any other desired purpose. zo The object of my invention is to overcome the practical difficulty inet with in interrupters which work in a vacuum or sealed receptacle when the operation of the interruptor is produced by an electroinagnet whose action z 5 is controlled by the action of the interruptor itself, the difficulty being that any impairy ment of the contacts will affect the operation of the magnet and that inasmuch as the contacts are sealed they cannot be gotten at for 3o repair or read j ustm ent without destroying` the receptacle.

My invention consists, essentially, in operating the interruptor by an electromagnet traversed by an alternating electric current passing over a circuit independent of that controlled by the interruplier-contacts.

My invention consists, i'urther, in special arrangements of devices whereby the interrupter may be operated by an alternating 4o current when the only source of energy at hand is a direct or continuous current.

In the accompanying` drawings, Figure l illustrates, diagrammatically, a general arrangement of apparatus embodying my invention. Figs. 2 and 3 illustrate modifications.

A indicates the interrupter (shown as a spring-interrupter) contained in a sealed and exhausted receiver or receptacle B and connected through wires sealed in the walls 5o thereof with the exterior circuit.

C is a contact-point mounted within the same and connected with the opposite pole of said circuit through a wire sealed in the wall ot the receptacle. The tension of the spring normally keeps the circuit closed, and at every vibration the circuit is interrupted, thereby producing a change of circuit condi` tion which maybe utilized for any purposeas, for instance, when the circuit is one of 6o induction, for setting up extra currents or electric disturbances or waves that may be employed, as set out in my prior patent, for producing light or for any other purpose.

D indicates a coil of induction included in the circuit 5, passing through the interrupter and carrying current derived from any suitable source.

E indicates the light or other translating device in a branch G, taken from said circuit, 7o so as to be traversed by the waves or pulsations setup by the interruption of the circuit of induction by the device B.

The interrupter A carries at its end an armature u, placed in the field of an electromagnet G, so that on energization of the magnet the vibrator will be drawn away from the contact C, and on a decrease or cessation of power in the magnet the spring will restore the circuit. 8o

The electroinagnet G is caused to vary in power by passing alternating electric currents through it. At each reversal when the magnet loses its power the vibrator will close its circuit, and in the intervals when the magnet 8 5 is energized, whether by a current of one or the other polarity, the armature a will be drawn down and the circuit interrupted. The electromagn et Gis in the circuit lO, connected with any source of alternating currents typi- 9o lied at I, said circuit being quite independent of that tlowing over the contact C. As will be obvious, the rate of alternations in the circuit lO will determine the rate of interruptionsin the circuit 5, and by varying the speed 9 5 of the generator of alternating currents the rate ot' interruption in 5 may be adj Listed as circumstances may require. The armature a might be polarized, if desired, but in such case it is obvious that the rate of Vibration would be decreased one-half, since at every other alternation of current in l0 the armature would be repelled instead of being pulled down.

In order 'that the number of interruptions may not be diminished and yet that the aetion of the vibrator may be positive in both directions, I may arrange the polarized armature of the interrupter between two magnetpoles which are reversed at each alternation of the current circulating in their energizingcoils, as indicated in Fig. 2, where for the sake of compactness and simplicity I prefer to use the opposite poles of the same magnet G, as indicated. rhe vibrator D is preferably loosely pivoted, as indicated, and works between the two contacts C, which are con neeted with one pole of the circuit, while the interrupterA con neets with the opposite pole. The coil G is in the alternating-eurrent circuit independent of that through A.

I do not limit myself to using a continuous current in the circuit of A, but might use an alternating current therein derived, if desired, from the same source as that flowing through G, but taken through an independent branch.

`When it is desired to operate the Vibrator from a direct-current circuit and yet to employ alternating currents for actuating the same whose rate of alternation may be controlled, I may employ such an arrangement as indicated in Fig. 3, where Il indicates any 1neter-transformer, one side of which is operated as a motor of the direct-current circuit l2, while its other side supplies alternating currents to the circuit l0, including the coils of the electromagnet G, which actuates the vibrator or interrupter A. This electromagnet G may itself be wound as a transformer or induction-coil and its secondary supply the current for the circuit of induction or other circuit which is interrupted by the action of A. In such circuit is included the coil of self-induction D, although such coil D might be dispensed with and the current of the secondary used Vfor operating on the light or other tanslating device E connected to the circuit.

It will be obvious that by varying the rate of movement of the transformer L the rate of alternation and the rate of action of the interrupter may be thereby varied, as occasion may require.

I do not limit myself to the use of a direct or continuous current in the circuit of induction which traverses the interrupter, for such current might be an alternating current and in this case might be taken from the same mains which supply alternating current to the interrupter-actuating magnet.

lVhat I claim as my invention isl. The combination, substantially as described, with an interrupter working in a sealed receptacle, of an aetuating-magnet therefor, and a source of alternating currents supplying said actuating magnet over a branch or circuit independent of thatineluding the contacts of the interrupter.

2. The combination, substantially as described, with an interrupter working in a sealed receptacle, of an electromagnet exterior thereto, a polarized armature carried by said interrupter, and asource of alternating currents with which said magnet is connected through a circuit independent of that ineluding contacts of the interrilpter.

3. rlhe coinbinatioil, substantially as described, of an interrupter working in a sealed receptacle between a pair of contacts, a polarized armature carried by said interrupter, a pair of actuating-magnet poles on opposite sides of said interrupter, and a source of alterna-ting currents` for said actuating-magnet supplying the saine over a wire or circuit independent of that including the contacts of the interruptor.

et. The combination, substantially as described, of an interruptor working in a sealed receptacle, an actuating-magnet therefor, a motor-transfornier haying a continuous-current side operating as a motor, of a directcurrent circuit, and an alternating-current side supplying the actuating-magnet for said interrupter over a circuit independent of that including the contacts of the interruptor.

Signed at New York, in the county of New Yori; and State of New York, this 22d day of November, A. D. 1895.
